7 Claims.

This invention has to do with vertically slidable sash of the type used.in the windows of railway cars, busses and other vehicles, and isparticularly concerned with the way in which the bottom rail sealingstrip is held in place.

The usual practice has been to provide a channel with inturned sideflanges on the lower edge of the bottom rail and fit into it a rubberstrip with undercut side grooves, relying upon the engagement of theflanges within the grooves to keep the strip in position. The troublewith this sort of mounting has been that at the ends of the bottom railwhere the rubber strip projects into the guides there is a pull on theends of the strip when raising the sash in closely fitting guides, whichpull frequently is enough to start one of the ends of the strip out ofthe channel, and when this once begins the strip will peel out with butvery little resistance. This difliculty 0 is particularly pronouncedwhere the sash is of the type in which a rubber or felt strip is mountedin or on the side rail for engagement with the guide, in which case theprojection of such side rail strip beyond the end of the bottom rail 2proper leaves the underlying end portion of the bottom rail sealingstrip without any supporting means.

The present invention resides in the provision of a simple but verypractical device, in the form of a corner clip, which will entirelyovercome this difficulty without requiring any changes and withoutadding appreciably to the cost of the sash.

While the foregoing statements are indicative of the nature of theinvention, other objects and advantages will be apparent to thoseskilled in the art upon a full understanding of the construction andfunction of this new device.

Two slightly diiferent embodiments of the invention are hereinillustrated and described, but

it will of course be appreciated that the invention is susceptible ofincorporation in still other structurally modified forms coming equallywithin the scope of the appended claims.

In the accompanying drawings:

Fig. 1 is an inside face view of one of the lower corners of avertically slidable metal sash, with the end of the sealing strip on thebottom rail of the sash clamped in place in accordance with theinvention;

Fig. 2 is an edge view of the sash structure shown in Fig. 1;

Fig. 3 is a vertical section through the sash, taken on the line 3-3 ofFig. 2;

Fig. 4 is a vertical section through the bottom rail and sealing strip,taken on the line 2-4 of Fig. 3;

Fig. 5 is a horizontal section through the side rail, taken on the line5-5 of Fig. 3;

Fig. 6 is a perspective view of the corner clip used in securing theextreme projecting end of the bottom rail sealing strip; and

Figs. 7 to 12 inclusive are views corresponding respectively to Figs. 1to 6 inclusive, showing a somewhat different embodiment of theinvention.

The sash which is illustrated fragmentarily in Fig. 1 has a sheet metalbottom rail it which contains a channel II in its lower edge for thereception of a soft rubber sealing strip 62. As is customary in sashstructures of this type, the side walls of the channel H are providedwith inturned flanges l3 which fit into undercut grooves [4 in the sidesof the strip. The strip I3 is inserted in the channel H eitherby-feeding it endwise into the same or else by tilting the strip to getone side in and then forcing the other side in with a suitable tool.

The bottom rail in is connected by a corner insert IE to a side rail it,which side rail, in the particular sash structure shown, is equippedwith a special side rail extension in the form of a soft rubber stripIT, in accordance with the teaching of Hamm Patent No. 1,981,355. Thestrip 9? is secured within a channel in the edge of the side rail IS inmuch the same manner as the strip 52, with the lower end of the strip l1overlying the unsupported end l8 of the strip l2 some little distancebeyond the end of the bottom rail 18.

Behind the rubber strips 92 and ll an L-shaped sheet metal member 2%! issecured about the sheet metal portions of the corner of the sash againstthe mitered ends of the bottom and side rails, being held in position bycertain of the screws 2| used to fasten the insert if: within the endsof the rails. The member 20, which is in the form of a narrow strip,coacts with the insert It: to hold the mitered ends of the rail snuglytogether, in accordance with the teaching found in the recently allowedapplication of William S. Hamm and Harry D. Sevison, Serial No. 698,032.

In carrying out the present invention, a tongue 22 may be out out of thecenter of the upwardly extending portion of the strip 2!! and projectedoutwardly and downwardly and caused to terminate in a reversely benthorizontally extending clip portion 23. This projecting clip 23 extendsinto a recess 24 near the end of the bottom rail sealing strip l2beneath the lower end of the strip l1 and by engaging with the uppersurface of the recess in a more or less resiliently clamped associationserves to hold the extreme end of the strip l2 snugly in positionagainst the bottom of the strip I! and prevent the end of the strip l2from being pulled out of position by reason of its frictional engagementwith the side walls of the guide.

While the clip 23 is shown as a part of the corner member 29, it will ofcourse beunderstood that it may be made as a separate part and that itis in no way dependent in the performance of its function on thepresence of the corner memher, the latter being used or not, as desired.Likewise, the herein disclosed feature of clamping up the end of thebottom rail sealing strip is obviously not limited in its application tothose sash structures which have side rail extension strips, as theretention of the sealing strip is 01' importance in other types of sash.

The retaining clip 23, in addition to keeping the end of the sealingstrip from being pulled out of its channel in the bottom rail, willprevent the strip from working endwise in either direction, it being ofcourse understood that it is desirable to use two clips to a sash, oneat each end of the bottom rail.

In the embodiment which is shown in Figs. 7 to 12 inclusive, a type ofsash structure is illustrated wherein no outside corner strap is used.In this case the retaining clip 25 may advantageously be formed on thelower end of a downwardly extending lip 25 on a sheet metal guideway 21provided for the latching bolt. In this embodiment it will be noted thatthe horizontally extending portion of the clip 25 projects into a slitwhich is provided for its reception in the upper or head portion of thesealing strip, rather than into the hollowed out lower portion of thestrip. As illustrative of the adaptability of this improvement to sashstructures of various kinds, it will further be noted that the side rail39 of the sash shown in connection with this embodiment is provided witha rib 3| on which a felt covered metallic channel member 32 is fastenedfor coaction with the usual guide, in accordance with the teaching inHamm and Sevison Patent No. 1,997,822.

I claim:

l. The combination, with the bottom rail of a sash having a channel withinturned side flanges, and a rubber sealing strip in the channel havingundercut side grooves for the reception of the flanges, of a clip at theend of the bottom rail which enters a recess in the end of the sealingstrip and bears upwardly against the upper surface of the recess.

2. The combination, with the bottom rail of a sash having a channel withundercut side flanges, and a rubber sealing strip in the channel havingundercut side grooves for the reception of the flanges, of a clip at theend of the bottom rail which projects downwardly and terminates in ahorizontally disposed portion which enters a recess in the end of thesealing strip and bears upwardly against the upper surface of therecess.

3. The combination, with the side rail of a sash having a projectingnon-metallic guide-engaging member, a bottom rail terminating short ofsaid projecting member, and a rubber sealing strip at the lower edge ofthe bottom rail projecting beyond the latter flush with said member, ofmeans carried by the sash beneath the end of the bottom rail sealingstrip for preventing the latter from'being pulled away from theoverlying lower end of the non-metallic side rail member by the frictionof the guides.

4. A sash provided with a bottom rail, a rubber sealing strip inengagement with the bottom rail, means coextensive with the rail forholding the strip against the rail, and other means extending beyond therail ends and engaging the strip for preventing the ends from beingpulled downwardly.

5. A sash provided with a bottom rail having a longitudinally extendingchannel therein, a rubber sealing strip in the channel and projectingbeyond the ends thereof, means in engagement with the strip for holdingthe latter in the channel, and other means hooked under the projectingends of the strip for preventing the ends from being pulled downwardly.

6. A sash provided with a bottom rail having a longitudinally extendingchannel therein, a rubber sealing strip in the channel and terminallyextending beyond the ends thereof, means extending the full length ofthe bottom rail in engagement with the strip for holding the latter inthe channel, and other means at the ends only of the strip in engagementwith downwardly facing surfaces of the latter for preventing the endsfrom being pulled downwardly.

7. A sash provided with a bottom rail having a longitudinally extendingchannel therein, a rubber sealing strip in the channel with the ends ofthe strip projecting beyond the ends of the rail, means extending thefull length of the rail in engagement with the strip for holding thelatter in the channel, and other means at the projecting ends only ofthe strip for preventing such ends from being pulled downwardly.
